The extravagant snail-house in Sofia`s district of Simeonovo is one of the local attractions. It represents colorful 5-storey building in the shape of a snail. Although its non-standard form, the building fits well the surrounding buildings and creating the illusion that the giant snail crawl along the street. On the roof are "perched" small ladybug and butterfly and around "crawl" other small snails.

The construction was built in 2008 and is owned by a construction specialist who designed the golf courses in Japan and France and worked over the palace of the Emir of Kuwait. The house is built in high quality of lightweight and environmentally friendly materials. There are no straight walls, corners and edges. It is claimed that in the construction was not used any brick.
